The student is able to: (1) characterize transmission environments and their effects on telecommunication signals, (2) create a channel model, (3) explain and apply methods of elimination of unwanted phenomena in the channel, (4) explain the ways of generating, transmitting and receiving telecommunication signals, (5) estimate the parameters of transmitted signals and use them for advanced methods of signal processing.

Knowledge of bachelor mathematics (integral calculus, solution of equations, fundamentals of probability analysis and statistics) and fundamentals of signal processing (convolution, correlation, filtering, spectrum analysis) are requested.
